The SSG Company makes basketballs and footballs. Each basketball requires 3 pounds of rubber and 4 square feet of leather, while each football requires 2 pounds of rubber and 5 square feet of leather. Each basketball produced results in a profit of $12, and each football earns a profit of $16.

Given that SSG has at most 800 square feet of leather and more than 500 pounds of rubber, formulate a linear programming model to identify the number of basketballs and footballs that should be produced to maximize total profit.

Answer :

Final answer:

To solve the problem, form a Linear Programming model. Define X as the number of basketballs and Y as the number of footballs. Maximize the profit equation: Maximize Z = 12X + 16Y. Add constraints based on the availability of resources which are created by the usage of each ball: 3X + 2Y <= 500 (Rubber) and 4X + 5Y <= 800 (Leather). Further ensure non-negative productions: X>= 0, Y >= 0. Then, graphically represent and solve for the maximum profit.

Explanation:

The subject here is based on Linear Programming, a mathematical approach typically used in Business or Economics to aid decision-making and resource allocation. To create a Linear Programming model for SSG Company's situation, we need to establish the variables, the objective function, and the constraints.

Let's define:

  • X = number of basketballs
  • Y = number of footballs

Then, the profit maximization equation (objective function) would be: Maximize Z = 12X + 16Y.

With the given company resources, our constraints are the maximum available resources they can use for production:

  • 3X + 2Y <= 500 (Rubber)
  • 4X + 5Y <= 800 (Leather)

And of course, the number of basketballs and footballs manufactured cannot be negative, we stack further constraints as X >= 0, Y >= 0.

From there, you will go through the process of graphical representation, identifying feasible regions, and then using the corner point method or the iso-profit method to find the profit-maximizing output level.
